Arftpplication-September28, 1945, SerialNozv619g218 (Cl. 248`z68) Another object of the invention resides inpro-` viding alsupport of the above-mentioned character `.which is simple and durablein construction,jreliable.and eflicient'in use and inexpensive to manufacture. I

Other objects and advantages of .the invention will be apparent Tduringthecourse of theffollow` ing description.

In the accompanying drawing forming a part of this specification and in which like numerals are employed to designate like parts throughout the same,

Fig. 1 is a front elevational view of the support positioned in a trench,

Fig. Z is a section taken on the line 2--2 of Fig. 1,

Fig. 3 is a Vertical sectional view of the support after the support is embedded in concrete, and,

Fig, 4 is a section taken on line 4-4 of Fig. 1.

In the drawing wherein for the purpose of illustration a preferred embodiment of the invention is shown the support is generally designated by the numeral 5 and consists of an upper supporting block 6, a lower supporting block l and intermediate spacing block 8. The blocks forming the support are rectangular shape and made of concrete with reinforcing rods 9 embedded in the center thereof, as shown in Fig. 3. When assembled the blocks are disposed in vertical spaced relation and have opposed recesses IIl formed in their confronting faces to receive the bre ducts II which carry the electric conduits.

A depending plate I2 is suspended from the center of the lower supporting block 1. The upper end of the plate is angularly bent, as at I3, to engage the side face of the block 1 to which it is attached by a bolt I4 passing transversely through the black. The blocks 6, 1 and 8 are held together in clamping engagement with the bre ducts II by a tie wire I5 which passes through an opening I6 in the plate I2 and ex- 55 *tends .up both sides .of-.the blocks with the free` endstwisted together, v.as at I1, over the topjof the upper.supporting.-block 6.

`Theanchoring means forsecuring the support `.in thevtrench' IB consists `of apair of arms I9 and 20 having .theirinner ends Vdisposed in overlapping` relation and Vtheir outerends twistedJ as at 2I, to form prongs .22 adaptedto penetrate the side Walls of .the trench. The overlapping `ends ofthe armsl I 9 and20 are adapted to receive Lthe ^depending .plate I2 of the. .support there--` between and `on each side ofthe plate the arms are secured` together by bolts 23land` 24 which upon tighteningfrmly clampthe arms and. plate together. Upon removalof either the bolt 23 or ZILtheremainingv bolt serves as a pivot to permit thelarmsto'be folded'preliminary to driving'the arms into engagement with the Walls of the..

trench.

When installing the support in a trench "the anchoring means isrst positioned in the bottom of thetrench `.by 4"folding Athe arms I9 and `2IJ which allowsthe .l arms to bellowered into the trench. AWith the prongs atthe ends of the arms in engagement with the trench Walls a force is applied to the arms above the pivot of the arms to spread the arms laterally and force the prongs to penetrate the walls until the arms are in a horizontal plane. After adjustment of the anchor arms the lower supporting block carrying the depending plate I2 is lowered in the trench with the plate inserted between the overlapped ends of the anchor arms. The supporting block 'l is adjusted vertically and sidewise to provide for proper alignment and grading of the conduits to be supported thereby and then the bolts 23 and 24 are tightened to firmly clamp the plate I2 between the anchor arms thus securing the block in its adjusted position. The conduits are then laid between the supporting blocks and secured together by the tie wire I5. After laying the conduits in the trench, the conduits including the support are completely encased in concrete 25 which is poured into the trench.

It is to be understood that the form of our invention herein shown and described is to be taken as a preferred example of the same and that changes in the shape, size and arrangement of the parts may be made within the scope of the subjoined claims.

Having thus described our invention, We claim:

l. A conduit support for laying conduits in a trench comprising opposed supporting blocks having recesses in their confronting faces to receive the conduits therein, means for securing said blocks in clamping engagement with said conduits, and anchoring means xedly attached to the center of the lowermost block composed of folding arms adapted to be spread into holding engagement with the walls of the trench.

2. A conduit support for laying conduits in a trench comprising opposed blocks having recesses in their confronting faces to receive the conduits therein, means securing said blocks in clamping engagement with the conduits, a plate depending from the center of the lowermost block and. x-

edly attached thereto, and anchoring means adjustable longitudinally of said plate adapted to engage the Walls of the trench..y

3. A conduit support for laying` conduits .in a trench comprising opposed blocks having recesses in their confronting faces toy receive the conduits therein, means securing said blocks in clamping engagement with the conduitsa plate depending from the center of the lowermost block and iixedly attached thereto, a pair of foldable anchor arms having their inner ends disposed in overlapping relation with said plate adjustably disposed therebetween, albolt pivotally connecting said arms together to jpe'rmitl spreading of said arms into engagementvvith the Walls of the trench and a second bolt forsecuring said arms in spread position and in clamping engagement with said plate. Y

4. A conduit support comprising a series of supporting blocks arranged in a vertical tier with opposed transverse recesses in their confronting faces ,toV receivethe conduits, means securing said blocks together and inclamping engagement withk the conduits, a plate fixedlyattached to the lowermost block and depending fromthe center thereof, and foldable 'arms adjustably connected to said plate adapted to be extended into gripping engagement with the Walls of a trench.

5. A conduit support for laying conduits in a trench comprising opposed supporting blocks having recesses in` their confronting faces to receive the vconduits therein, means securing said blocks in clamping engagement with saidv conduits, and

vertically folding arms adjustably attached` to the lowermost block adapted when extended to engage the Walls of the trench.

6. A conduit support as described in claim 5 including means for securing said arms in extended position.

7. A conduit support for laying conduits in a trench comprising opposed supporting blocks having recesses in their confronting faces to receive the conduits therein, means securing said blocks in clamping engagement with said conduits, a

stem depending from the lowermost block and around said blocks and throughv an opening in said anchoring post.
